characterized in that the shaft means (3) comprises a tubular
shaft to which the arm system (1, 2) is attached and which is
pivotably journalled on a rod extending from one locking
element (4) to the other.
5. Mechanism according to claim 1 or claim 2,
characterized in that the shaft means (3) comprises a tubular
shaft to which the arm system (1, 2) is attached and which is
pivotably journalled on pivot pins attached to and extending
towards each other from the respective locking elements (4).
6. Mechanism according to any of claims 1 to 5,
characterized in that the center height (h) of the shaft
means (3) above the underside of the container (5) or the

WO 93/12996 PCT/NO92/00203
like is less than the length (1) of the said further arms (2)

than the length (L) of the said first arm (1).
7. Mechanism according to any of claims 1 - 6,
characterized in that the said further arms (2) are arranged
symmetrically about a plane at right angles to the shaft
means a mid-length thereof.
8. Mechanism according to any of claims 1 - 7,
characterized in that the said further arms (2) are provided
with rollers (6) or the like at their free ends.
9. Mechanism according to any of claims 1 - 7,
characterized in that the said further arms (2) are provided

MECHANISM FOR LEVE~ING AND HAULING OF A CONTAINER OR THE LIKE
The present invention relates to a mechanism for levering
and/or hauling of a container or the like.
Containers and similar loading bodies, incl. loading pallets,
are increasingly used for transport and storage of various
goods. This use is however of restricted value in locations
having reduced accessibility for lifting and shifting means,
because it may be c.fficult to deliver and remove the
container from such locations using the normal container
removal vehicles.
I~ is an object of the present invention to overcome this
difficulty and to permit the use of container transport and
storage even in locations where such transport and storage
was not convenient.
Thus, the invention aims at a mechanism for levering and
hauling of a container or the like, by means of which the
container may be levered from the gro~-d and subsequently
hauled onto e~g. a ramp or a tipping body of a lorry by means
of a simple hauling mechamism and without the use of a
special li~ting g~ar. Alternati~ely, the ramp or the tipping
body may be moved in under the container body.
The invention is characterized by the levering and hauling
mechanism comprising a pivotable system of arms which are
attached to a shaft means at different radial directions with
respect to the shaft means, and locking means to secure the
shaft means to the lower corners at one end of the container
or the like.
Further features of the invention will be apparent from~the
claims and the following description, reference being made to
the accompanying drawing showing an embodiment by way of
example.

2 I;~i
The drawing shows a levering and hauling mechanism comprising
a pivotable system of arms 1, 2 which are attached to a shaft
means 3 at different radial directions with respect to the
shaft means. Further, the shaft means 3 is provided with
locking elements 4 to secure the shaft means to the lower
corners at one end of a container 5 or a similar loading
body. The locking elements 4 may be of the type known for
locking containers of the like ship's decks etc.
The arm system comprises a first arm 1 located at mid-length
of the shaft means 3 and intended to be connected to a winch
or similar hauling mechanism by means of a wire or the like.
The said arm shall consequently be referred to as a "hauling
arm". The arm system further comprises one or more arms 2,
there being two such further arms 2 in the embodiment shown.
These further arms 2 will, when the hauling arm 1 is pivoted
under the influence of the hauling mechanism, be pivoted to
the ground, thereby levering container end from the ground.
These further arms 2 shall consequently be referred to as
"levering arms".
The shaft means 3 is pivotably connected to the locking
elements 4 by means of pivot pins. In an alternative
embodiment the shaft means may be in the form of a hollow
shaft iournalled on pivot pins extending from each locking
; element or on a rod extending from one locking element 4 to
the other.
In the mounted non-active state of the mechanism o~ the
invention, the hauling arm 1 extends substantially vertically
upward while the levering arm(s) 2 extend forward and
downward from the container 5. The length L of the hauling
arm 1 is usually greater than the length 1 of the levering
arm(s), in order to provide a re~uired moment to lever the
container from the ground. The mechanism of the invention is
mounted on the container with such a height h of the center
line of the shaft means 3 above the underside of the
container bottom and with respect to the levering arm length

l that the levering arm 3 may cause a levering of the
container end a distance l - h sufficiently to allow the
container end to be hauled directly in onto the end of a ramp
or a tilted tipping body.
;
The levering arm(s) 2 are conveniently provided with a roller
6 or the like at its free end, in order to allow the
container 5 to be hauled along the ground or in order to
allow a ramp or a tilted tipping body to be moved in under
the container end once the container is levered from the
ground.
The mechanism of the invention may alternatively be provided
with skids or the like at the free ends of the levering arms
2.
.~
Independently of whether the levering arms (2) carry rollers
(6) or skids at their free ends, the mechanism of the
invention may be advantageously used for shifting containers
from one location to another ln regions which are not easily
accessible with heavy haulage vehicles and/or heavy lifting
gear. The mechanism may also advantageously be used for
releasing a container or the like which is frozen or stuck to
the ground.
